HDI (High-Density Interconnect) PCBs represent advanced printed circuit board technology designed for densely packed components and high-speed signal transmission. These boards enable greater functionality and miniaturization in electronic devices through specialized manufacturing techniques.

• Microvias: Smaller, densely packed via structures (typically <150μm diameter)
• Sequential Build-Up: Layers laminated individually for increased density
• Laser Drilling: Precision creation of complex interconnect patterns
• High-Frequency Performance: Optimized for high-speed data transmission
• Miniaturization: Enables compact device designs

• Mobile Devices: Smartphones, tablets, wearables
• Computing & Networking: Servers, routers, data centers
• Medical Equipment: Diagnostic machines, monitoring systems
• Automotive Electronics: ADAS, infotainment systems
• Aerospace & Defense: Avionics, radar systems
• Industrial IoT: Automation, smart devices

While offering significant benefits, HDI PCB implementation in automotive applications presents unique challenges:

• Reliability under harsh environmental conditions
• Maintaining signal integrity with high-speed data
• Effective thermal management in compact spaces
• Complex manufacturing processes
• Cost considerations
• Regulatory compliance requirements
